From 80f8cfe29ace49167c1ad6439ddd15519b0a5455 Mon Sep 17 00:00:00 2001 From: Vladimir Serbinenko Date: Thu, 18 Feb 2016 20:26:44 +0100 Subject: [PATCH 1/6] mkimage.c: Split into separate files. util/grub-mkimagexx.c is included in a special way into mkimage.c. Interoperation between defines makes this very tricky.
